ESTIMATING THUNDERSTORM PENETRATIONS OF THE TROPOPAUSE,
Abstract
Data sources for radar measurements of thunderstorm penetrations of the tropopause level outside the United States are listed, but large areas will not be covered in any event. Two studies suggest that the sole use of low level moisture or the maximum amount of energy available to a storm as determined from a sounding will not be successful in estimating the distribution of penetrations above the tropopause level. An equation of the form Y = Ae exp. - Bx was found to fit the cumulative distribution of penetrations of the tropopause level to a high degree at all the stations studied. A method of estimating the cumulative frequency of penetrations based on a determination of the highest penetration likely to occur and the equation mentioned above gave good results for two widely separated stations in the United States having different thunderstorm climatologies.
